More than 70 fossilised trails of some of the earliest moving animals known, dating from around 565 million years ago, have been discovered by scientists embedded in rocks in Newfoundland. The trails show that these early organisms moved across the seafloor like modern anemones.
It is the first proof that animals from this early period of the earth's history had muscles that let them move around, and it is believed that the organisms probably had a muscular disc-shaped 'foot' to get around on. These early fossils pre-date the 'Cambrian Explosion' between 488 and 542 million years ago when a lot of new species appeared on earth. Experts had previously believed that animals alive before the Cambrian stayed attached to one spot and were like a static fungi.
